NPE during creation of a property for a specific class

[PhantomYdn]

OrientDB Version: 2.2.22

Java Version: 7+

OS: linux

It seems that OrientDB doesn't like class with name "Report". After creation of such class there are lots of interesting stuff is happening. And the only one solution: rollback to previous backup.

Creation of a new property for class "Report" or attempt to retrieve newly created class lead to the NPE in the same place.

Creation of property:

java.lang.NullPointerException

If "Report" is so specific - please make it a keyword.

@PhantomYdn just to clarify is it 2.2.2 version?

[PhantomYdn]

I'm sorry - you are right. I meant 2.2.22

[andrii0lomakin]

@PhantomYdn do you have broken database, which you are talking about? Do you have logs from this database? Preferably since the creation of a class Report? That is very important.

[PhantomYdn]

Backup was provided through Skype.

[andrii0lomakin]

Fixed. @santo-it description for release notes "In early versions of OrientDB deleted files did not preserve their ids correctly, as result after upgrade to latest version and creation of the cluster with the same name all cluster files are assigned the same id, so one file overwrites another file in file system and created cluster contains incomplete information about its state. "

@Laa , thank you a lot!
